Abstract (en)

[origin: US2008211322A1] The invention relates to a multipolar, linear or rotating synchronous direct drive motor which comprises a primary part and a secondary part. The primary part comprises a yoke and a plurality of teeth and slots interposed between said teeth, and winding strands of a polyphase winding running inside the slots. Between two winding strands of the same phase order the winding strands of the other phase or phases are disposed so as to overlap them. The secondary part is arranged opposite the primary part and comprises a plurality of permanent magnets of changing polarities on a common reflux base. The slot exits have an even slot pitch T<SB>N</SB> and the permanent magnetic poles have an even pole pitch T<SB>P</SB>. According to the invention, the winding strand of a respective phase winding consists of a continuous highly flexible braided wire, said braided wire being guided through the slots so as to meander around a group of teeth. The entire winding of a respective phase is configured by the braided wire which is arranged in layers in the respective slots. Every slot has a width that corresponds to the diameter of the insulated braided wire. The braided wires of the winding strands of the remaining phase or phases are guided between the slots of the first phase in a symmetrically off-set relation thereto. The layer structure of the winding of the meshed meandering winding strands results in flat winding overhangs having a small volume in the area of the points of intersection of the partial windings outside the slots.
